It is not dev's fault that the game isn't downloading. Either it's your browser, internet connection or the itch servers that cause the download to fail. It's in no way your computer's fault. The download isn't working as planned nor the dev's fault. I'm literally in the middle of nowhere right now on vacation and there is basicly no cellular connection out here and our wifi is poor AF too. Yet still, I manage to download the game in a few minutes, no issues. What so ever. The issue lies with either you or Itch.io, not the devs as they're not the ones managing the downloads, that's Itch.io.
